--------------------------------------
The patch looks good, thanks Heath :)
Could you create a patch for the 2.2.x and 2.3.x branches as well?
Also a patch for our documentation would be great to have.
Cheers,
Jamie

> When using the org.apache.karaf.main.DefaultJDBCLock class together with
> PostgreSQL, you can run into this exception (caused by the setQueryTimeout()
> method not being implemented yet - http://jdbc.postgresql.org/todo.html):
> {noformat}
> Failed to acquire database lock: org.postgresql.util.PSQLException: Method
> org.postgresql.jdbc4.Jdbc4PreparedStatement.setQueryTimeout(int) is not yet
> implemented.
> {noformat}
> We should at the very least document that the timeout should be set to 0 for
> PostgreSQL, but perhaps we'd better create a new JDBC lock implementation
> that hides this bit of knowledge from the users and provides them with a nice
> and easy way to use PostgreSQL for JDBC locking.
